GEORGE L. VHITE, OF OATON, NEV YORK.

SPECIFICATION forming part of Letters Patent No. 367,687, dated August 2, 1887.

` Application tiled September 2Q, 1886.

To all whom, it may concern:

vin the county of Steuben and State of 'New revolves.

`is complete] y governed.

York, have invented a new and useful Wind` mill, of which the following is a specification.

My invention relates to improvements in wind wheels or mills in which a series of vertical fans are attached near their. extremities t0 a series of horizontal arms in such amanner as to automatically present their faces to the wind, in connection with an automatic brake, by the action of which the speed of the mill I attain this object by the mechanism illustrated in the accompa nying drawings, in which- Figure l is aperspective of a windmill embodying my invention, a portion being broken away so as to show the other parts m ore clearly.-

Fig. 2 is an enlarged perspective of the operating parts. Fig. 3 is avertical section of the brake.

G represents the vertical shaft, which is journaled in suitable bearings in the derrick, and to which the arms X X are rigidly secured, so as to revolve therewith.

Hinged to the outer ends of the arms X X,

at a a, are the fans V, which are made to openv and close in the usual manner. NVhen they are closed, the shaft is made to revolve bythe pressure of the wind against them, and when they are open they present their edges to the wind, and the shaft ceases to revolve.

Connected to the fans V V are the jointed bars Y, which are hinged to the front edges of the fans at b,and are provided with the notches d at their inner ends. The inner ends of the bars Y pass through the perforated boards L, which are placed vertically between the arms X X, and which boards serve as guides to the movements of the bars. Pivoted upon the boards L are latches Z, which engage with the notches d in the bars Y, for the purpose of holding the bars forced outward, thereby locking the fans V in an open position. When the ends of the bars Y are forced inward, so

that the notches fZ do Vnot engage with the` latches Z, the fans V are closed and the wheel XVhen the bars are forced outward, so that the latches Z catch in the notches CZ, the

Serial No. 214.284. (No model.)

fans are held open, so as to present only their edges to the wind, and hence thewheel is brought to a stand.

Secured to the shaft at a suitable distance below the wheel is a casting, S, which forms a ci rcnlar track, M, and from which radiate the arms T, one for each set of fans. Secured to the outer end ot` cach arm T, in suitable sockeis provided therefor, are the vertical rods O, which are provided with projections c. These rods O extend up past the vertical boards L, and are connected thereto, as shown in Fig. 2. The projections e extend j ust under the lower edges of the bars Y, so that when the rods O are forced upward these projections force the bars Y upward with them, so as to engage the latches Z wit-h the notches cZ. The-upper ends of the two rods O are connected together by means of the rod orbar F,which extends across under the casting E upon the top of the shaft G. The other two rods, Q, extend upward a suitable distance along the vertical boards L, but are not connected together. Pivoted to the inner end of the operating lever P is the rod N, which has a frictionroller, g, journaled in its upper end, and which roller bears against the under side of the track M. When the lever l? is operated by means of the cord R, which extends down near the ground, the brakecasting S is forced upward, thereby raising the rods O with it, and thus causing the rods O to operate the inner ends of the bars Y by means of the projections e and force the ends of the bars upward in the slots in the boards L, so that the notches d will engage with the latches Z, and thus lock the fans in an open position;

Placed loosely upon the top of the shaft G is a casting, D, which is provided with a projecting rigid socket for the arm of the vane A and a hinged socket, O, for the arm ofthe vaneB.

To an arm projecting from the socket is loosely attached the connecting-rod p, which is fastened at its lower end to the casting E. The casting E may have a` rib or flange, mi, formed across its top, and this rib will catch in a corresponding socket formed in the bottom of the casting D, and thus keep the two parts always in their proper relative positions. The metallic rod or bar F, which unites the IOO upper ends of two of the rods O, is placed loosely upon the shaft G, and is provided with a head which revolves in the casting E, as shown in Fig. 3. The vane A, by standing with the wind, serves to hold the vane B with its face to the wind. Should a blast of wind strike the vane B, it would turn backward in the direction of the vane A, as shown by arrows in Fig. 1, and thus raise the casting E and bar F by means of the connectingrod P. As the bar F rises it operates the brake-casting S and causes all four of the rods O to move upward, thereby forcing the inner endsof the' bars Y in contactwith the latches, thus bringing theinill to a stand. Vhen the violence of the wind abates, the weight of the casting E and bar F, forcing downward upon the rods O, would cause the brake-casting S to drop downward, thereby withdrawing the prongs e from under the bars Y, leaving the inner ends of the vane to sink downward out of contact with the latches Z, unlatching the vane and allowing the mill to resume work. The

vane upon the arni B is held in any desired position by means of the set-screw J, thus enabling the vane to be set at any desired angle to the wind, and thereby regula-ting the -aniount of pressure the wind shall bring to bear upon the vane.

For the sake of convenience the casting E is made in two parts, and each part is provided with ears K, through which bolts are passed for the purpose of securing the two parts together;

Having thus described my invention, I clainil. The combination of the vertical shaft, the arnis X, secured thereto, the fans V, hinged to the arms XX, the bars Y, connected to the fans and provided with notches, the slotted guides through which the inner ends of the bars pass, the latches pivoted to the guides for engaging with the notches, the casting S,which is vertically adjustable upon the shaft, the rod O, provided with projections e, and a vane mechanism, substantially as shown, for operating the rods O and the bars Y, substantially as shown.

2. The combination of the vanes A B, pivoted socket C, castings D E, connecting-rodi), bar F, vertical shaft G, arms X., rods Y, having the fans V connected thereto and provided with the notches d, the slotted boards L,latches l, rods O, and casting S, substantially as described.
